RELATED ISSUES: This project was a major retrofit project prompted by findings of elevated levels of pollutants, including Polycyclic Aromatic Hydrocarbons (PAHs). It is located in a tributary leading down to Barton Creek which discharges approximately 300 feet above Barton Springs Pool. The project consisted of the removal of contaminated sediment, construction of a sedimentation/ filtration pond and the rerouting of storm water to a drainage ditch downstream of Barton Springs Pool in Zilker Park.
